Title: Friction shock absorbing mechanisms
IPC: B61G9/18
Filed: 1947-04-01
Abstract: 622,614. Springs ; vibration - dampers. MINER, Inc., W. H. April 1, 1947, No. 8843. Convention date, Nov. 29, 1946. [Class 108 (iii)] The case A of a friction shockabsorber has at its open end inwardlyprojecting lugs 13, behind which engage corresponding lugs 15 on a wedge block B,. the inner ends of the latter lugs and the outer faces of friction shoes C, having correspondingly inclined faces 17, 18, Fig. 7, in order to guide the lugs of the wedge behind those of the case during assembly of the mechanism. In operation the outer faces of each of the three V-shaped friction shoes engage the inner surface of the thickened end 11 of the hexagonal case A, while the inner inwardly inclined faces 20 engage corresponding V-shaped faces 14, Fig. 3, cut on the inner end of the wedge B; inward movement of the wedge forces the shoes to engage the walls of the case and also to move inwardly against the action of inner and outer springs D which bear on them. During assembly, the springs D are placed in the case A and the shoes C inserted so as to rest on the springs. The wedge B is then placed so that the bevelled face 17 of each lug 15 rests on the inclined edge 22 of a shoe C but is circumferentially away from the corresponding lug 13 on the case. On forcing the shoes C into the case against the springs, the lugs 15 slide down the inclined surfaces 18 and finally engage behind the lugs 13 on the case. The springs are then allowed to force the shoes C and wedge B in the outward direction until the lugs 13, 15 abut, and the upper edges 18 of the shoes C have risen above the lugs 13. In this position, each lug 15 is held in the peripheral space between two adjoining shoes 13, which are prevented from rotating by the shape of the case, and further outward movement of the block B is prevented.

Title: Method of improving pretzel products
Inventor: APPLEBY JOHN J
IPC: A21B5/02
Filed: 1967-02-24
Abstract: A pretzel, baked from pretzel dough and having a relatively hard texture core with a skin crust thereon formed in baking, is cooked in an edible cooking oil for a time and at a temperature sufficient to permit the oil to fully penetrate the crust and render it substantially impermeable to moisture, while reducing the moisture content of the core and rendering it softer, but crisp, and finally cooling and drying the so-cooked pretzel.  The preferred oil is coconut oil.  Preferably the pretzel is first immersed in the hot oil, preferably at about 225 DEG F., to melt off the predetermined amount, preferably 50%, of the salt from the pretzel crust, and is then immersed in hot oil at a lower temperature, preferably about 205 DEG F., to effect the penetration of the crust.  This may be effected by lifting the pretzels through a bath wherein the bottom is hotter than the top.  The oil may contain flavour ingredients, and, after removal from the oil, there may be applied to the pretzels flavourings containing salt, such as onion and garlic powders.

The wire 3 is coated by dipping it in the composition 8 and, after drying, one or more layers 9, 10 are formed by dipping in a slow-burning composition comprising red lead and coarse silicon in the same binder as the primer. After drying, the fuzehead is dipped in a deflagrating mixture comprising charcoal and potassium chlorate in an amyl acetate/nitrocellulose solution and dried before dipping once in collodion and four times in a solution comprising amyl acetate, amyl alcohol and nitrocellulose. High tension fuzeheads may be made in the same way, the bridge wire 3 and recess 5 being omitted and the primer being semiconducting. The slow-burning red lead and silicon composition may be replaced by a composition comprising zinc oxide, copper oxide and boron in the nitro cellulose binder. One layer of the slow-burning red lead and silicon composition may be used covered by two layers of a composition comprising zinc oxide and boron in a binder. The slow-burning composition may comprise bismuth powder mixed with finely ground selenium powder or antimony pentoxide mixed with manganese in a nitro-cellulose binder. Lead monoxide and silicon may form the bases of the slowburning composition. Finely ground silica may be incorporated in the red lead and coarse silicon composition. Lead dioxide may replace red lead in the priming composition
